Over a period of only a few days the boat had been attacked by a USAAF B-24 Liberator while hunting convoy TF-2, then came an attack by a B-18 aircraft,
and finally squadron VP-94's Catalinas located the U-boat and after one unsuccessful attack another VP-94
aircraft managed to sink it.

The commander and 2 other crew members were fished out of the sea, by the US Navy vessel Siren (former luxury yacht) that was part of escort for convoy TJ-4, after 17 days. Müller was severly wounded in this action and was repatriated to Germany in March 1944 as he was no longer capable of combat. He served as a liason to German U-boat men for the rest of the war.

20 Jul 1943The boat was attacked for the second time in two days by an American aircraft (Sqdn VP-94), which called in another aircraft, but U-662 again escaped. The boat was lost in a third attack the next day. (Sources: Blair, vol 2, page 369)
